What is Normal Body Temperature Range?
Our body controls the temperature within a narrow range by means of a process called thermoregulation. This is crucial as temperature affects the enzyme activities and chemical reactions of the body. The body temperature is measured with the help of a thermometer that is calibrated either in a Celsius scale or Fahrenheit scale. By normal body temperature range, we mean the range of temperature that is optimal for carrying out the bodily functions and metabolic activities. Low temperature (hypothermia) or high temperature (hyperthermia) without any apparent reason can be a sign of underlying disease. Read more on types of thermometer. The body temperatures of a person vary significantly, depending upon various aspects, like the body area for measurement, the time of the day and the level of physical activity. To be more precise, rectal and internal body measurement is slightly higher then body surface measurements. The lowest body temperature is measured around 3 a.m. in the morning, wh
